The data for moon rise and set times appear to be in error when
compared to US Naval Observatory ephemeris. Also, for a date of
October 2, 2004 when changing between 4:10PM and 4:11PM the
rise time for the moon changes from 8:30PM to 9:03PM. Lat/long
inputs are 37d9m N and 76d23m W and I am manually adjusting
for daylight savings time. I have version 2.5.1 and version 4.1 of
the Palm OS.
